The problem with this woman spouting racism, whereas it is more likely incompetence, is that it undermines and drives a divide.
Far better if she simply pushed the fact the software was not fit for purpose, less people would switch off and support her I suspect.
But people like her just cant help it. They do not represent the majority of Black people though, working in London I met loads and not one blamed anything on racism that I can recall even after a skinfull of beer!
